Pow3r77 Control - Home Assistant on your wrist

Four full-screen buttons. Each one triggers an automation in your Home
Assistant: lights, blinds, a goodnight scene, whatever you like. Tap, the watch
buzzes, done.

HOW IT WORKS
The app sends a request to a Home Assistant webhook. You decide inside Home
Assistant which automation or script that webhook runs, so the app needs to
know nothing about your home, and changing what a button does never requires
reinstalling anything.

WHAT YOU NEED
- A Home Assistant instance reachable over HTTPS from the internet (Nabu Casa
  or a reverse proxy). Plain http is not allowed by Garmin.
- One automation with a "webhook" trigger per command, with local_only turned
  off: the request leaves from your phone, so Home Assistant sees it as coming
  from outside your local network.
- In the app settings: the Home Assistant address, plus a name and a webhook id
  for each button.

DETAILS
- Works by touch or by buttons: UP and DOWN move the selection, START runs it.
  The fenix touchscreen is disabled during activities and when the screen is
  locked, so everything must be reachable without it.
- Different vibration for success and failure, so you know the outcome without
  looking.
- Errors are spelled out: webhook not found, no connection, or the response
  code.
- An unconfigured button stays greyed out and inert instead of failing when
  pressed.
- After a confirmed command the app closes itself.

PLAIN WARNINGS
The webhook id is stored in the Connect IQ settings, which are kept in clear
text and synchronised through Garmin's servers. A webhook is not full account
access - it triggers one automation and cannot read or control anything else -
but anyone who knows it can fire that automation. Use long, random ids, and
think twice before binding something sensitive, such as opening a gate or a
door, to a button.
